This looks really good, have you maybe tested it with Newton and Unified Plugin? I'd like to try it with UCS-B VLAN mode... @SNArchsCOM

If you´re doing an upgrade just for the sake of it - I think it might be better to wait for the 3.0, I had a sneak peak, and its finally looking decent. On the other side, if you need new features, like AppStore on ACI or similar, you can upgrade, we´ve had 2.2 for a while, and its pretty stable.

Ok, so I had this defined before, and I got a new Mac, and now I cant remember how exactly I did it... basically what happens now when I enter the SAMPLES and try to run any of the .py, I get: MatBook-Pro:samples mjovanovic$ python tutorial.py Traceback (most recent call last): File "tutorial.py", line 30, in <module> from acitoolkit.acitoolkit import * File "/Users/mjovanovic/acitoolkit/acitoolkit/__init__.py", line 31, in <module> from .acisession import EventHandler, Login, Session, Subscriber # noqa File "/Users/mjovanovic/acitoolkit/acitoolkit/acisession.py", line 46, in <module> from six.moves.queue import Queue ImportError: No module named queue MatBook-Pro:samples mjovanovic$ PS. I have credentials.py in all the required folders.

You´re the man. Two things to have in mind here: 1. Specify the correct speed using the "speed" command 2. Make sure the SFP is Cisco: Nexus-5548-Geo2# show interface e1/11 transceiver detail Ethernet1/11 transceiver is present type is 10Gbase-SR name is CISCO-FINISAR part number is FTLX8571D3XXX-XX revision is A serial number is FNS17230WSF nominal bitrate is 10300 MBit/sec Link length supported for 50/125um OM2 fiber is 82 m Link length supported for 50/125um OM3 fiber is 300 m Link length supported for 62.5/125um fiber is 26 m cisco id is -- cisco extended id number is 4 SFP Detail Diagnostics Information (internal calibration) ---------------------------------------------------------------------------- Current Alarms Warnings Measurement High Low High Low ---------------------------------------------------------------------------- Temperature 49.75 C 75.00 C -5.00 C 70.00 C 0.00 C Voltage 3.20 V 3.63 V 2.97 V 3.46 V 3.13 V Current 8.48 mA 11.80 mA 4.00 mA 10.80 mA 5.00 mA Tx Power -1.88 dBm 1.69 dBm -11.30 dBm -1.30 dBm -7.30 dBm Rx Power N/A -- 1.99 dBm -13.97 dBm -1.00 dBm -9.91 dBm ---------------------------------------------------------------------------- Note: ++ high-alarm; + high-warning; -- low-alarm; - low-warning

Well this is dissapointing... noone anwered in 6 months, and I have the exactly same problem...

mateja.jovanovic · ‎07-16-2015

You probably managed to solve this, or gave up, but when the Port goes to a SUSPENDED state (s) - there is a difference in the physical or config layer, something like speed and/or duplex, so make sure that on "show interface" on all Port-channel members you have the same speed, and if not - revise the cable/other side/patch pannels. Hope this helps :)

mateja.jovanovic · ‎06-01-2015

wow... 2 months and not a single answer... a bit disappointing... The same question I posted on the WireShark forum... there was a bit more luck there, but still confused why Nexus shows the errors in the statistics... https://ask.wireshark.org/questions/40756/how-do-i-make-sure-if-tcp-retransmissions-are-actually-not-fake

mateja.jovanovic · ‎06-01-2015

Thanks for the answer Pieterh, but I don´t really think this is the case, as we have 2 DHCP servers, but in the Active/Standby architecture. Now, regarding your proposal to "wait untill the iPhone decides to send a new request instead of renewal", I'm not sure I get what you mean, How exactly would I configure this? Thanks

mateja.jovanovic · ‎05-25-2015

Hi Scott, It happens with all iPhones 5 and 6, regardless of the firmware (haven't tried with iPhone 4 or iPads they are not used in clients corporate network). As users get closer to the elevator zone, while using the WiFi and surfing the internet, a roaming occurs and a request for the authentication (user/password request) suddenly appears. Once they re-authenticate, everything continues normally. Sometimes this happens when switching the AP, sometimes it does not, haven´t been able to figure out a rule.

mateja.jovanovic · ‎04-25-2015

Nice tool... but for 30 euros I think I´ll stick to the instructions provided by John here below :)

mateja.jovanovic · ‎04-23-2015

Another Cisco Partner, our direct competition from which we "stole" the client? No... haven't contacted them :)

mateja.jovanovic · ‎04-23-2015

I wish... here is the answer I got from TAC: " in this case there is nothing we can do to replace it as per Cisco policies and procedures customer has to engage his reseller for support. " So disappointing... Now I need to call the client and tell them they need to throw the lifetime warranty switch away and buy a new one...

mateja.jovanovic · ‎04-22-2015

A simple question: Our client has 3560X Switches with a limited lifetime warranty. The Cisco Partner with whom they had the contract before bought the equipment, and they did not end up on good terms. One of the devices died the other day. My question is - how do we replace it now? Thanks

mateja.jovanovic · ‎04-15-2015

I tried the same thing, but there is no way to run the ACI simulator without the additional HW. You have all the info here: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/simulator/getting-started/b_ACI_Simulator_Getting_Started_Guide.pdf

Hi, So we´ve been having this performance issue, and on the capture I can see that maybe 50% of the DC to Core traffic are Out ot Order and TCP Retransmissions. Cisco Nexus device also shows many of these in the Socket Statistics (does someone know how the N5k actually manages to qualify them as retransmissions, how fiable is this?). I do have the same TCP flow going over the same psyical link towards the Checkpoint FW and back to the Core, and then over to the server... but how can I actually be sure if the TCP Retransmissions are not just the members of the same IP flow but detected twice? How does Wireshark detect the Out of order and Retransmission, there is no flag for that, so... some inside intelligence? And even if WireShark is wrong... is Nexus wrong too showing 50% packets as retransmissions in "show socket statistics" output?
